Synchrotron radiation from auroral electrons

The techniques previously used to calculate the synchrotron radiation from an artificial belt of trapped particles are applied to the case of radiation from particles spiraling about the magnetic field lines over the auroral zone. The results are presented in terms of various combinations of particle energies and intensities that would provide an observable signal in the upper HF to lower VHF band. Although the required intensities are considerably higher than the intensities normally present according to available satellite measurements, it is concluded that the mechanism does offer a possible explanation for some of the previous observations of auroral noise during very severe disturbances.
